Abstract
A method of producing macroporous carbon capsules includes providing pollen grains from date palm (L.) males, drying the pollen grains, heating the dried pollen grains to a temperature of at least 500° C. under an atmosphere of Ngas to produce macroporous carbon capsules. The macroporous carbon capsules produced from the above method can have an oval shape with a diameter in the range of about 18 μm to about 20 μm. The macroporous carbon capsules have a mean pore diameter in the range of about 50 nm to about 450 nm. The pores are three-dimensionally interconnected via nanoscopic carbon walls. The carbon walls have a thickness of about 4 μm.
